Explanation:

An orphan record are records that have been left out of the new system when a company changes its model of operation since they have no transition path. Therefore the best way to prevent this would be to create a master-detail relationship to represent the one-to-many model of engines to parts. This would allow these records to be captured and reprocessed into the new system that the company has moved to in order for them not to be left out.
